Question about 1998 Plymouth Voyager

1 Answer

I hav e a 1998 Plymouth Grand Voyager. Great Car..runs good. Drives great. Instrumentation Panel went dead. ABS Light comes on and off. Service Engine Soon Lite comes on and off. Air Bag lite comes on and off. Diagnostics show many error messgaes reported from several modules (BCM Messages, PCM Messages, Transmission Control Module Messages). Feeling is that computer card could be the problem. What is the name/part number of the computer card for this vehicle? Can it be replaced? Where can I find the right card? thanks..chet brion

There is no one computer control module for the whole car, there is the Body control module that operates the power accessories and the instrument cluster and other functions like wipers and the anti theft system, it is called the BCM, there is a ABS control module (sold with the entire ABS hydraulic control unit), then the Airbag/SRS system has what is called the Airbag diagnostic monitor module, the Transmission control module called the TCM, and the Powertrain control module (PCM) are all contained in the same module, the chances that all these control modules have failed is next to zero, the most cost efective thing to do at this point is to have the Chrysler dealer diagnose all the fault codes you are receiving, even if it proves that one or more of the control modules is defective you can't just plug them in, they must be programmed for your car by the dealer using a special tool called a scanner.

    I hope you've fixed your problem. My experience with this same van is the problem is bad solder connections, specifically the 13 pin wiring harness connector on the instrument panel circuit board. Re-melting these pins on the circuit board itself will probably fix your problem. I had a continuing problem that I finally traced to a 330 ohm resistor on the body control module circuit board. This resistor is labeled 331, and I simply re-melted the solder on both ends of this resistor. (I would have replaced it if I had a suitable one) Haven't had any of the recurring electrical problems since.

Break light not working on a 1998 plymouth grand voyager expresso

If you are saying the brake light and parking light on one side is dead, the problem would be in the socket or the ground connection.
There would be two different circuits involved. And the rear parking lights are powered by the same fuse as the front.
The brake lights are on one fuse too.

Kill switch on 1998 plymouth grand voyager

Just because the lights go on does not always mean that the battery has enough power to engage the starter. The clicking noise could be the voltage regulator clicking. And since you disconnected the battery maybe there is not a great connection at the terminals. Were the terminals cleaned before the battery was reconnected?
Curious ... what was the cause of the check engine light going on?

1998 Plymouth Grand Voyager.........Dashboard instruments quit working and don't light up. Speedo, tach, fuel gauge, temp gauge, and mileage indicators and lights for same stopped working. ABS...

You have some wiring problems shorting out that is coming from the dash board so if you or anyone you know how to use a multimeter to check the wireing harnesses plus check any connectors that might be just very touching the connector of dashboard which means a bad connection to dashboard.

Alarm is going off and the Plymouth Grand Voyager won't start.

Try using your key (after reconnecting battery) on the drivers door, to lock, and unlock it. There are so many different vehicles with different methods, you may have to call dealer service dept, with your VIN # and name, and they should be able to give correct procedure to disarm security system. Check owners manual as well.
